摘要： An igniter for a spark ignition system includes a support body fabricated from an electrically insulating material and a metal casing disposed outwardly of and at least partially surrounding the support body. The metal casing has a structure for connecting the metal casing to ground. At least two rod-shaped first electrodes are supported one relative to another by the support body and are electrically isolated one from the other by the support body. Each first electrode has a first end that protrudes from a first end of the support body at a spark forming end of the igniter. The support body is disposed at least partly within an axial channel of a generally cylindrically-shaped second electrode. The second electrode projects past the support body at the spark forming end of the igniter and cooperates with the first ends of the at least two first electrodes to define at least two spark gaps. The second electrode is electrically isolated from the metal casing by an air gap. During use the first electrodes receive a first voltage that is higher than ground and the second electrode receives a second voltage that is lower than the first voltage. A first spark is formed within a first one of the at least two spark gaps and a second spark is formed within a second one of the at least two spark gaps.

摘要： A multi-electrode spark plug having a large spark target volume is disclosed. The spark plugs have a plurality of ground electrode rods which extend from the base of the spark plug and are twisted around center electrode to provide a plurality of substantially equidistant spark points relative to the center electrode. The spark points are formed in parallel and around the elongated axis of the spark plug. This configuration enables the spark to be created where the localized concentration of fuel to air is richer, such as that which may exist when the engine is operating with lower revolutions per minute. Test results indicate that automobiles equipped with the multi-electrode spark plugs exhibit improved fuel economy, and substantially reduced emissions and air pollution.

摘要： A spark plug includes a tubular housing, a tubular insulator retained in the housing, a center electrode secured in the insulator with a distal end portion of the center electrode protruding outside the insulator, and an annular ground electrode fixed to a distal end of the housing. The housing has, at the distal end thereof, a small-inner diameter portion that has a smaller inner diameter than other portions of the housing. The annular ground electrode is arranged on a distal end surface of the small-inner diameter portion of the housing so that an inner circumferential surface of the ground electrode faces an outer circumferential surface of the distal end portion of the center electrode through a spark gap formed therebetween. The outer diameter of the ground electrode is less than the outer diameter of the distal end surface of the small-inner diameter portion of the housing.
